         <title>Watch This: Non-Stick Coating Keeps Ketchup Flowing &amp; Airplane Wings Free of Ice | 80beats</title>

         <description>&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Let&amp;#8217;s face it, ketchup bottles suck. When you get down to an almost empty the bottle, plastic ones burp and splat all over your clothes, and glass ones have you awkwardly &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Heinz_Tomato_Ketchup#Glass_bottle_design"&gt;whacking the &amp;#8220;57&amp;#8243;&lt;/a&gt; on the Heinz bottle. That&amp;#8217;s why this video of ketchup sliding effortlessly with a tip wrist is so impressive&amp;#8212;even surreal.&lt;/p&gt;
&lt;p&gt;This little bit of magic is the effect of &lt;a rel="nofollow" target="_blank" href="http://mit100k.org/bpc/bpc-semi-finalists/liquiglide/"&gt;LiquiGlide&lt;/a&gt;, a superslippery coating developed by physicists at MIT. The &lt;a rel="nofollow" target="_blank" href="http://varanasi.mit.edu/"&gt;lab headed by Kripa Varanasi&lt;/a&gt; initially began researching coatings that could &lt;a rel="nofollow" target="_blank" href="http://www.economist.com/blogs/babbage/2012/04/oil-production"&gt;prevent clogs in deep sea oil pipes&lt;/a&gt; and ice from sticking to airplane wings. &lt;a rel="nofollow" target="_blank" href="http://www.newscientist.com/article/dn20947-carnivorous-plant-inspires-superslippery-material.html?DCMP=OTC-rss&amp;amp;nsref=online-news"&gt;Other research groups&lt;/a&gt; have also come up with nonstick coatings that follow the same broad principle: the coating is actually a thin layer of liquid, which allows things to slip right off.&lt;/p&gt;
&lt;p&gt;Getting the coating into ketchup bottles meant an extra hurdle because the materials had to be food safe. The scientists are keeping mum about what the coating is actually made of&amp;#8212;a patent is in the works&amp;#8212;but they promise it&amp;#8217;s all FDA-approved materials.&lt;/p&gt;
&lt;p&gt;And if you prefer your fries &lt;a rel="nofollow" target="_blank" href="http://dutchfood.about.com/b/2008/03/04/ill-have-mayonnaise-with-my-fries.htm"&gt;in the Dutch style&lt;/a&gt;, don&amp;#8217;t worry: LiquiGlide handles mayonnaise just as well.&lt;/p&gt;

         <title>Synthetic Biologists Turn DNA Into Rewritable, Digital Data Storage | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/YcqmXJEsRgQ/</link>
         <description>&lt;p class="imgcapright"&gt;&lt;img src="http://blogs.discovermagazine.com/80beats/files/2012/05/shutterstock_93597241-e1337697834337.jpg" alt="DNA"/&gt;&lt;/p&gt;
&lt;p&gt;DNA is a great way to store information&amp;#8212;just ask your cells. Its molecules are stable, and billions of base pairs coil neatly into a few microns in a cell nucleus. While it&amp;#8217;s easy for a cell to read information from DNA, a cell can&amp;#8217;t rewrite new data into its DNA sequence.&lt;/p&gt;
&lt;p&gt;But now synthetic biologists at Stanford have managed to pull off that very trick. To do so, they had to abandon the genetic code of ATCG and get a DNA sequence to act like bits&amp;#8212;pieces of binary information&amp;#8212;in a computer. The memory system uses two enzymes that can cut out and reintegrate a sequence of DNA in a live cell. Crucially, the attachment sites are designed so that the DNA sequence can be flipped every time it is put back in. The sequence oriented one way would represent 1, and its inversion is 0.&lt;/p&gt;
&lt;p&gt;This may sound unnecessarily convoluted and maybe even a little inefficient&amp;#8212;this DNA &amp;#8220;bit&amp;#8221; took three years to engineer&amp;#8212;but synthetic biologists have something bigger brewing on their hands. By working out the pieces of a biological circuit, they hope to get cells to perform computations. A DNA bit, for example, can be used as a counter for ...

         <title>Impatient Futurist: Your Domestic Robot Servant Has Finally Arrived (in a Fashion) | DISCOVER</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/yCcBSsshZXA/11-impatient-futurist-your-domestic-robot-arrived</link>
         <description>&lt;img src="http://discovermagazine.com/2012/may/11-impatient-futurist-your-domestic-robot-arrived/humanoid.jpg" alt="robotic helping arms" align="right"&gt;
&lt;p&gt;Like many people with limited social skills, i’ve always wanted a robot. And I’ve never been the least put off by the strict movie rule that having a robot can only result in its owner being pushed down the stairs, sucked into the vacuum of outer space, or enslaved with what’s left of humanity. I’m well aware that movie rules are hardly ever wrong, but it hasn’t been fear of betrayal that’s kept me from having a robot helper. It’s been the lack of their existence, in spite of a century of big talk. And this has left me not only without the sort of non–emotion-experiencing companion who could really understand me but also with a lot more laundry, cooking, dirty dishes, and child care than a technophilic citizen of the 21st century should have to put up with.&lt;/p&gt;
&lt;p&gt;Useful home robots have always been about 20 years in the future, according to experts—a discouraging estimate, since the same experts assure me every other exciting technology under development is only 5 years away. Yes, I know, you can drive over to Walmart and pick up a carpet-vacuuming “robot” to keep your lawn-mowing “robot” company. While you’re there, why don’t you also grab a “house” in the camping department? I’ve got no interest in keeping company with hundreds of dumb, whirring little things. Scampering scrubbers and pot-stirrers are way too small and stupid to push me down the stairs when I’m not looking.&lt;/p&gt;
&lt;p&gt;I’m hardly more impressed with the current small crop of machines that fall into the category of sticking a laptop on a wheeled dress mannequin and calling it a robot. The best you’re going to do there is &lt;a rel="nofollow" class="external-link" target="_blank" href="http://robodynamics.com/"&gt;Luna&lt;/a&gt;, a human-size “robot” that will soon be widely available from a company called &lt;a rel="nofollow" class="external-link" target="_blank" href="http://en.wikipedia.org/wiki/RoboDynamics"&gt;RoboDynamics&lt;/a&gt; in Santa Monica, California, for $3,000—incredibly cheap for a humanoid, but incredibly expensive for a device that can’t do much more than try not to bump into furniture and senior citizens as it desultorily wheels itself around your home, toting a tray of drinks you’ve carefully placed on its precarious, pipe-like arms...&lt;/p&gt;

         <title>Japan Is Now Running on 0% Nuclear Power. That Means Using More Fossil Fuels. | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/dW32q7ueD3c/</link>
         <description>&lt;p class="imgcapright"&gt;&lt;img src="http://blogs.discovermagazine.com/80beats/files/2012/05/fukushima.jpg" alt="fukushima"/&gt;&lt;br /&gt;
The Fukushima Daiichi power plant in 1975, seen from above.&lt;/p&gt;
&lt;p&gt;As of this weekend, when Tomari Nuclear Power Plant was shutdown for maintenance, &lt;a rel="nofollow" target="_blank" href="http://www.cnn.com/2012/05/07/world/asia/japan-nuclear-energy-ends/?hpt=hp_c2"&gt;every last one of Japan&amp;#8217;s 54 nuclear plants have Japan has been taken offline&lt;/a&gt;. Although the shutdowns are supposed to be temporary, after &lt;a rel="nofollow" target="_blank" href="http://blogs.discovermagazine.com/80beats/tag/fukushima-daiichi/"&gt;the power utilities&amp;#8217; mismanagement of the Fukushima disaster last year&lt;/a&gt;, the Japanese public has registered increasing distrust for official reassurances that nuclear power can be safe. These shutdowns could conceivably become permanent.&lt;/p&gt;
&lt;p&gt;The world&amp;#8217;s major economies all use nuclear power to some extent, and Japan, which got about 30% of its power from reactors, was one of the heavier users before the the Fukushima meltdown. Now, public opinion there and the world over has soured toward nuclear power, to the extent that &lt;a rel="nofollow" target="_blank" href="http://www.businessinsider.com/german-nuclear-wind-energy-2012-1"&gt;Germany has officially announced plans to abandon nuclear completely by 2022&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;As Bryan Walsh at TIME Science &lt;a rel="nofollow" target="_blank" href="http://www.time.com/time/health/article/0,8599,2114166,00.html?iid=tsmodule"&gt;points out&lt;/a&gt;, though, this backlash against one of the few high-output energy sources that does not involve fossil fuels comes with a price.&lt;/p&gt;
&lt;blockquote&gt;&lt;p&gt;Japan&amp;#8217;s business community and its government have warned that the country could face serious energy shortages this summer without nuclear power, which could dent the world&amp;#8217;s third largest economy ...&lt;/blockquote&gt;

         <title>Gross But Cool: Weaving Blood Vessels with Threads of Human Tissue | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/QIuGfXIaqL0/</link>
         <description>&lt;p class="imgcapright"&gt;&lt;img src="http://blogs.discovermagazine.com/80beats/files/2012/05/threads.jpg" alt="vessels"/&gt;&lt;br /&gt;
This machine is weaving 48 strands of human connective tissue together into a tube.&lt;/p&gt;
&lt;p&gt;Growing fresh blood vessels is a much fantasized-about goal of biomedical engineers. It sounds vaguely vampiric, but the idea is to replace the veins in the arms of &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Hemodialysis"&gt;dialysis patients&lt;/a&gt;, which are a mess from being breached several times a week to be hooked up to a blood-cleaning machine. From there, engineers hope to provide off-the-shelf replacements for heart valves and such.&lt;/p&gt;
&lt;p&gt;Most approaches involve getting human cells&amp;#8212;either donor cells or cells from the patient&amp;#8212;to manufacture &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Extracellular_matrix"&gt;rubbery connective tissue&lt;/a&gt; made of proteins, from which the cells are stripped away to avoid an immune reaction in patients. Some companies start with flat sheets of this tissue and roll them into tubes, while &lt;a rel="nofollow" target="_blank" href="http://www.technologyreview.com/biomedicine/32264/"&gt;others have the cells make the stuff around a tubular mold&lt;/a&gt;. One company, though, is trying out a technique that made us look twice. They&amp;#8217;re &lt;a rel="nofollow" target="_blank" href="http://www.technologyreview.com/biomedicine/40348/page1/"&gt;weaving the vessels from thread spun with thin strips of cultured connective tissue&lt;/a&gt;, Technology Review reports.&lt;/p&gt;
&lt;p&gt;The hope is that given manufacturers&amp;#8217; copious experience with machine weaving, these woven structures could be easier to mass-produce than the tubes made with other techniques. Though there isn&amp;#8217;t much ...

         <title>Big Idea: Physicists Carve a Niche in Time | DISCOVER</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/byGiyYXzHeY/08-big-idea-physicists-carve-a-niche-in-time</link>
         <description>&lt;img class="inline" src="http://discovermagazine.com/2012/apr/08-big-idea-physicists-carve-a-niche-in-time/time.jpg" alt="light &amp; time" align="left"&gt;
&lt;p&gt;Physicists routinely baffle reporters, but for once things went the other way. &lt;a rel="nofollow" target="_blank" href="http://focus.aep.cornell.edu/people.html" class="external-link"&gt;Alexander Gaeta&lt;/a&gt; was sitting in his Cornell University office in the fall of 2010 when a reporter called to ask his opinion of a &lt;a rel="nofollow" target="_blank" href="http://iopscience.iop.org/2040-8986/13/2/024003" class="external-link"&gt;strange new paper&lt;/a&gt; in the &lt;i&gt;Journal of Optics&lt;/i&gt;: What did he think about the claim that it might be possible to create a time cloak, a device that would render events undetectable?&lt;/p&gt;
&lt;p&gt;Gaeta was caught off guard. He was still grappling with the invisibility cloak, a wild idea that turned into reality in 2006, when physicists demonstrated that a &lt;a rel="nofollow" target="_blank" href="http://www.sciencemag.org/content/314/5801/977" class="external-link"&gt;class of synthetic materials could bend light completely around an object&lt;/a&gt;. (Think of water in a stream flowing around a rock.) Without light bouncing off the object, it would essentially disappear.&lt;/p&gt;
&lt;p&gt;But creating a time cloak–something that could hide not just an object but an event–is even more ambitious. Rather than just rerouting the rays of light striking an object, a time cloak would have to deflect all the light beams influenced by the object as it moves through space. The time cloak would, in essence, create an interval during which all information about what an object is doing disappears.&lt;/p&gt;
&lt;p&gt;Although Gaeta had not heard of the time-cloak study until that phone call, he dove into it as soon as the reporter sent it over. The author, theoretical physicist &lt;a rel="nofollow" target="_blank" href="http://www3.imperial.ac.uk/people/m.mccall" class="external-link"&gt;Martin McCall&lt;/a&gt;&amp;nbsp;of Imperial College London, proposed splitting a light beam into two segments moving at different speeds. As one fragment built a lead on the other, a gap of complete darkness would open up between them. Anything happening within that gap, McCall reasoned, would be impossible to detect, since there would be no light to scatter. Then, to complete the trick, McCall proposed bringing those two segments back together so that by the time the beam of light reached an observer, there would be no way to detect that the gap ever existed...&lt;/p&gt;

         <title>Hot Science: Real-World Technology That Approaches "The Avengers" | DISCOVER</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/gNff8AM9A-E/01-real-world-technology-that-approaches-the-avengers</link>
         <description>&lt;p&gt;After a series of solo adventures, Marvel’s greatest superheroes will finally join forces on the big screen this Friday, May 4. In anticipation of the Avengers’ suiting up to save the day, we took a look at how today’s technology stacks up against the best weapons wielded by our favorite superhumans.&lt;/p&gt;
&lt;p&gt;&lt;i&gt;&lt;b&gt;Iron Man&lt;/b&gt;&lt;/i&gt; &lt;br&gt;Super Tech: A bespoke high-tech exoskeleton not only protects billionaire Tony Stark from supervillains, it also lets him fly faster than the speed of sound, lift up to 100 tons, and confirm dinner reservations through his AI assistant.&lt;/p&gt;
&lt;p&gt;Real-World Tech: U.S. soldiers may soon have robotic exoskeletons of their own. Defense giant Lockheed Martin’s model, now in testing, supports soldiers as they run at speeds of up to 10 miles per hour while carrying 200 extra pounds.&lt;/p&gt;
&lt;img src="http://discovermagazine.com/2012/may/05-hot-science/captam.jpg" alt="Thor and Captain America"&gt;
&lt;p&gt;&lt;i&gt;&lt;b&gt;Captain America&lt;/b&gt;&lt;/i&gt; &lt;br&gt;&lt;i&gt;Super Tech:&lt;/i&gt; The Captain’s shield, made of an alloy with the alien metal vibranium, absorbs kinetic energy—so the strain of battle only makes it stronger.&lt;/p&gt;
&lt;p&gt;&lt;i&gt;Real-World Tech:&lt;/i&gt; Scientists have yet to find a material that gets tougher from taking a hit. But in 2011 researchers at Lawrence Berkeley National Lab unveiled the strongest, toughest substance ever: a microalloy of glass and the rare metal palladium...&lt;/p&gt;

         <title>Sourcemap: Slick App for Tracking the Supply Chain for Your Laptop (or Tuna or Nutella) | 80beats</title>

&lt;p&gt;If you&amp;#8217;ve ever wondered where all the parts in your laptop came from, take a second to look at this &lt;a rel="nofollow" target="_blank" href="http://sourcemap.com/view/744"&gt;map&lt;/a&gt;&amp;#8212;or maybe a few minutes, because it is a dense, complicated web. &lt;a rel="nofollow" target="_blank" href="http://sourcemap.com/"&gt;Sourcemap&lt;/a&gt;, which has its origins in MIT Media Lab, is a new open source website for mapping global supply chains and carbon footprints. There are also Sourcemaps for &lt;a rel="nofollow" target="_blank" href="http://sourcemap.com/view/2187"&gt;Chicken of the Sea&amp;#8217;s tuna&lt;/a&gt; and &lt;a rel="nofollow" target="_blank" href="http://sourcemap.com/view/2542"&gt;Nutella&lt;/a&gt; among others.&lt;/p&gt;
&lt;p&gt;Although the site seems to have been conceived as a way of keeping track of modern corporations, some of the most intriguing maps are historical ones. Take this supply chain for &lt;a rel="nofollow" target="_blank" href="http://sourcemap.com/view/2239"&gt;Western Electric&amp;#8217;s candlestick telephones from 1927&lt;/a&gt; or this overview of &lt;a rel="nofollow" target="_blank" href="http://sourcemap.com/view/2126"&gt;international trade in 19th century London&lt;/a&gt;. The beauty of open source projects is that they can go off in unexpected and delightful directions.&lt;/p&gt;
&lt;p&gt;But as &lt;a rel="nofollow" target="_blank" href="http://www.fastcoexist.com/1679754/track-where-your-stuff-comes-from-down-to-the-tiniest-part"&gt;Ariel Schwartz at Fast Company has pointed out&lt;/a&gt;, Sourcemap also suffers from that plague of open source sites, quality control. Go to the &lt;a rel="nofollow" target="_blank" href="http://sourcemap.com/browse"&gt;browse&lt;/a&gt; tab, and you&amp;#8217;ll immediately be finding yourself among maps titled &amp;#8220;Test 123,&amp;#8221; &amp;#8220;farting robot,&amp;#8221; or &amp;#8220;My stuff.&amp;#8221; Hopefully, Sourcemap will come up with way of rating and verifying the quality of ...

         <title>Wash, Catalyze, Rinse, Repeat: Getting Filth-Munching Enzymes to Stick Around | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/IZcovD3_pDE/</link>
         <description>&lt;p class="imgcapright"&gt;&lt;img src="http://blogs.discovermagazine.com/80beats/files/2012/05/laundry-e1335887977749.jpg" alt="spacing is important"/&gt;&lt;/p&gt;
&lt;p&gt;The best way to get rid of dirty laundry stains&amp;#8212;think grease or blood or grass streaks&amp;#8212;is using &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Biological_detergent"&gt;enzymes&lt;/a&gt; that chew the oil, sugar, and protein molecules in those stains right up. Enzymes are catalysts, which means they help the breakdown of molecules but they don&amp;#8217;t get broken down themselves. A protease will cleave a protein, emerge unscathed, and then happily go on to cleave another protein, again and again. But the enzymes that come in most laundry detergents get thrown out with each laundry load&amp;#8212;tossing the enzyme-baby out with the washing machine water.&lt;/p&gt;
&lt;p&gt;Two chemists in Indian have found a &lt;a rel="nofollow" target="_blank" href="http://pubs.acs.org/doi/abs/10.1021/ie202053r"&gt;way to reuse those enzymes&lt;/a&gt;. Using some chemistry know-how, they found a way to make enzymes stick on a type of cheap, common plastic called PVC. The Economist&amp;#8217;s &lt;a rel="nofollow" target="_blank" href="http://www.economist.com/blogs/babbage/2012/04/washing-enzymes?fsrc=gn_ep"&gt;Babbage&lt;/a&gt; blog breaks down how the method works:&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;blockquote&gt;&lt;p&gt;The two researchers checked that by conducting the sort of test often seen in adverts for washing powder. They placed white cotton cloths stained with starch, grass, egg or mustard oil into the [enzyme-coated PVC] beaker. They then washed the cloths with cheap, non-enzymatic detergents inside the enzyme-coated beaker and compared the result with similar washing done ...&lt;/blockquote&gt;

         <title>Impatient Futurist: Your Personal, Automated Mass Transit Vehicle Is on Its Way | DISCOVER</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/lMlc6isCUbw/12-impatient-futurist-personal-automated-mass-transit</link>
         <description>&lt;img src="http://discovermagazine.com/2012/apr/12-impatient-futurist-personal-automated-mass-transit/impatient.jpg" alt="futuristic mass transit" align="right"&gt;
&lt;p&gt; Despite my mania for all manner of irresponsible personal vehicles, I’m actually a public-transportation nut. A few of the reasons:&amp;nbsp;&lt;br&gt;•&amp;nbsp;I can read, check email, send text messages, or catch a few winks while I’m zipping to my destination &amp;nbsp;&lt;br&gt;•&amp;nbsp;I have built-in motivation for walking, given that I have to get to and from the bus or train stop&amp;nbsp;&lt;br&gt;•&amp;nbsp;I feel good that my ride isn’t fueled by the conversion of fossilized sea life into impending climate catastrophe&amp;nbsp;&lt;br&gt;•&amp;nbsp;I get to trade small talk and occasional newspaper sections with fellow transit riders.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;But I know you have your very good reasons for being among the 98 percent of the population that shuns public transportation:&amp;nbsp;&lt;br&gt;•&amp;nbsp;You can read, check email, send text messages, or catch a few winks while you’re swerving into oncoming traffic and pedestrians &lt;br&gt;• You have built-in motivation for stopping at Wendy’s for celebration takeout, given that you haven’t had to walk more than nine consecutive steps the entire day &lt;br&gt;• You feel good about the copious burning of hydrocarbons, which is creating valuable new beachfront property &lt;br&gt;• You get to trade hand gestures and occasional gunfire with fellow traffic jammers.&lt;/p&gt;
&lt;p&gt;Ok, go ahead and sneer at my bus through the windshield of your Range Rollover. Thanks to some snazzy high-tech upgrades coming to public transit over the next several years, I’ll have the last laugh. Surely you’d envy me, for example, were my bus to suddenly lower four large metal wheels next to its tires and jump onto nearby rail tracks to go roaring off past your Toyota Highballer and all the other traffic. Or were my bus to pass over the roof of your Porsche Careen, supported on giant stilts with wheels that ran on either side of the road. Or, perhaps most impressive, were my commuter train to fly by you—really, actually fly by, lifted a few feet in the air by side-mounted wings.&lt;/p&gt;
&lt;p&gt;Well, get ready to gawk. The next time you’re in Asia, that is, because the &lt;a rel="nofollow" target="_blank" href="http://www.wired.com/autopia/2008/05/half-bus-half-t/" class="external-link"&gt;track-riding bus&lt;/a&gt; and the &lt;a rel="nofollow" target="_blank" href="http://spectrum.ieee.org/automaton/robotics/industrial-robots/ground-effect-robot-could-be-key-to-future-high-speed-trains" class="external-link"&gt;flying train&lt;/a&gt; are Japanese projects in prototypes (at Toyota and Tohoku University, respectively), and a &lt;a rel="nofollow" target="_blank" href="http://www.nytimes.com/2010/08/18/business/global/18bus.html" class="external-link"&gt;stilted bus&lt;/a&gt; has been developed in China...&lt;/p&gt;

         <title>Hundreds of Delicate Spirals on Martian Surface Indicate a Volcanic Past | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/nQyTl66dNqs/</link>
         <description>&lt;p&gt;&lt;img src="http://blogs.discovermagazine.com/80beats/files/2012/04/lavacoils1smaller.jpg" alt="spacing is important"/&gt;&lt;/p&gt;
&lt;p class="imgcapright"&gt;
&lt;p&gt;The &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/HiRISE"&gt;HiRISE camera&lt;/a&gt; orbiting Mars spotted 269 of these beautiful coils on the surface of the Athabasca Valles Region of the Red Planet. The patterns, which range from 15 to more than 90 feet wide, seem to be larger versions of those sometimes observed on Earth after a volcanic eruption; they can arise when two lava flows going in opposite directions curl around each other, or when the molten lava rotates slowly because of differences in the density or viscosity of two intersecting flows. There has been debate among scientists over whether the region&amp;#8217;s unusually patterned surface was formed by ice or lava, and &lt;a rel="nofollow" target="_blank" href="http://www.sciencemag.org/content/336/6080/449"&gt;the publication of these images in this week&amp;#8217;s &lt;em&gt;Science&lt;/em&gt;&lt;/a&gt; adds credence to the lava theory.&lt;/p&gt;

         <title>The Real Problem with Driverless Cars | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/Cw_w7Hcwc4o/</link>
         <description>&lt;p&gt;&lt;/p&gt;
&lt;p&gt;When &lt;a rel="nofollow" target="_blank" href="http://www.forbes.com/sites/alexknapp/2011/06/22/nevada-passes-law-authorizing-driverless-cars/"&gt;Nevada made driverless cars legal in the state last year&lt;/a&gt;, we armchair futurists sat up a little straighter. All of a sudden &lt;a rel="nofollow" target="_blank" href="http://blogs.discovermagazine.com/80beats/2011/05/23/google-tries-to-jump-start-the-driverless-car-but-big-questions-loom/"&gt;a number of meandering philosophical questions about how our society would have to change to embrace such technology&lt;/a&gt; seemed quite a bit more urgent. This question seemed especially pressing: Driverless cars are safer than those piloted by humans, but how would we feel about deaths caused by machines rather than people?&lt;/p&gt;
&lt;p&gt;In our post on the topic &lt;a rel="nofollow" target="_blank" href="http://blogs.discovermagazine.com/80beats/2011/05/23/google-tries-to-jump-start-the-driverless-car-but-big-questions-loom/"&gt;we considered the ethics of the situation&lt;/a&gt;, but we think &lt;a rel="nofollow" target="_blank" href="http://www.popsci.com/cars/article/2012-04/who-blame-when-robotic-car-crashes"&gt;this recent short piece&lt;/a&gt; from Popular Science nails the liability angle on the issue: the real question, as far as car manufacturers are concerned, is not whether the cars are fundamentally safer, but who will should take legal responsibility for the accidents:&lt;/p&gt;
&lt;blockquote&gt;&lt;p&gt;When a company sells a car that truly drives itself, the responsibility will fall on its maker. “It’s accepted in our world that there will be a shift,” says Bryant Walker Smith, a legal fellow at Stanford University’s law school and engineering school who studies autonomous-vehicle law. “If there’s not a driver, there can’t be driver negligence. The result is a greater share of liability moving to ...&lt;/blockquote&gt;

         <title>Handicap breeds excellence? | Gene Expression</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/MbDmnS6i6wg/</link>
         <description>&lt;p&gt;There&amp;#8217;s a &lt;a rel="nofollow" target="_blank" href="http://www.laweekly.com/2012-04-12/film-tv/35-mm-film-digital-Hollywood/4/"&gt;wide-ranging story&lt;/a&gt; in &lt;i&gt;LA Weekly&lt;/i&gt; on the decline of 35mm film. It covers a lot of angles, but this one issue jumped out at me:&lt;/p&gt;
&lt;blockquote&gt;&lt;p&gt;No wonder, then, that directors like Christopher Nolan worry that if 35mm film dies, so will the gold standard of how movies are made. Film cameras require reloading every 10 minutes. &lt;b&gt;They teach discipline. Digital cameras can shoot far longer,&lt;/b&gt; much to the dismay of actors like Robert Downey Jr. — who, rumor has it, protests by leaving bottles of urine on set.&lt;/p&gt;
&lt;p&gt;&amp;#8220;Because when you hear the camera whirring, you know that money is going through it,&amp;#8221; Wright says. &amp;#8220;There&amp;#8217;s a respectfulness that comes when you&amp;#8217;re burning up film.&amp;#8221;
&lt;/p&gt;&lt;/blockquote&gt;
&lt;p&gt;This particular variant of critique of new technologies is very old. It is famously well known that writing and printing both ushered in warnings that these were simply crutches, and might diminish mental acuity. &lt;b&gt;But I&amp;#8217;m 99% sure that when bow &amp;#038; arrow become common, some hunters warned that the skills and traditions associated with the &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Atlatl#History"&gt;atlatl&lt;/a&gt; would decay.&lt;/b&gt; The piece highlights some genuine advantages of analog over digital. I do not think making filming more difficult is an advantage, to state the obvious.&lt;/p&gt;

         <title>Spy on the Inside: Underground Control Center for Texas' Power Grid | DISCOVER</title>

&lt;p&gt;This room may look unfamiliar, but it is one of the most  important places in your life. Without it, you could not count on your house being warm and bright, your food staying safe in the fridge, or your ability to charge your iPad or cell phone. Behind the modern world is a vast wired network transmitting electricity to consumers. We call it the grid, but it is not as neat and orderly as the name implies. The hodgepodge of connections evolved over 100 years from a patchwork of local networks, interstate transmission lines, and ad hoc fixes. It is divided into three parts—the Eastern Interconnection, the Western Interconnection, and Texas. Pictured here is the &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Grid_(electricity)" class="external-link"&gt;grid control center&lt;/a&gt; for the &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Electric_Reliability_Council_of_Texas" class="external-link"&gt;Electric Reliability Council of Texas&lt;/a&gt;. Generators and distributors of electricity depend on it to communicate and to prevent leaving customers with too much or too little power. The result would be a blackout. Even with control centers, the grid still flounders. Texas experienced blackouts in February 2011, as colder-than-average winter weather simultaneously increased demand for electricity and damaged coal-fired power plants and wind turbines. During the summer, demand for air-conditioning threatened a series of near blackouts. Operators in the control room can adjust some conditions, but eliminating the grid’s instability would require big change.&lt;/p&gt;

         <title>Computers Can Grade Essays As Well As People Can | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/ZiRtSJ4VzxY/</link>
         <description>&lt;p class="imgcapright"&gt;&lt;img src="http://blogs.discovermagazine.com/80beats/files/2012/04/scores2.jpg" alt="grades"/&gt;&lt;br /&gt;
RS is the average of scores given by two human readers;&lt;br /&gt;
all the others are computer programs.&lt;/p&gt;
&lt;p&gt;To anyone who&amp;#8217;s ever written an essay for a standardized test&amp;#8212;be it the SAT, the ACT, the GMAT, or others&amp;#8212;it should come as no surprise that getting a high-scoring essay is a matter of following a formula. The SAT is not the time to show off your lyrical ability or demonstrate your awareness of the nuances of morality: when the prompt is &amp;#8220;Is it better to have loved and lost than never loved at all?&amp;#8221; it&amp;#8217;s hard to argue &amp;#8220;It depends&amp;#8221; in 25 minutes. Just take a stance, come up with two supporting examples, and hammer that baby out.&lt;/p&gt;
&lt;p&gt;Turns out, though, that standardized test essays are so formulaic that test-scoring companies can use algorithms to grade them. And before you get worried about machines giving you a bad score because they&amp;#8217;ve never taken an English class, said algorithms give the essays the same scores as human graders do, &lt;a rel="nofollow" target="_blank" href="http://dl.dropbox.com/u/44416236/NCME%202012%20Paper3_29_12.pdf"&gt;according to a large study that compared nine such programs with humans readers&lt;/a&gt;. The team used more than 20,000 essays on eight prompts, and you can see in the figure ...

&lt;blockquote&gt;&lt;p&gt;Large companies have overheads, a necessary evil, you say. Overheads need to be managed. And managed they are: Group Managers, Program managers, General managers, together with ‘Senior’ flavours of those and a whole new breed of directors, stakeholders, business owners, relationship leads coupled with their own countless derivatives.&lt;/p&gt;
&lt;p&gt;All those meeting-goers are not making anything. Deciding upon and making something is hard. And if this onerous activity has to be done, then hire external consultants for it. It’s easier and less risky.&lt;/p&gt;
&lt;p&gt;There is no creative tension, no vision these days. Left to Microsoft’s hands we’d still be toiling on overheating Vista desktops.&lt;/p&gt;
&lt;p&gt;This company is becoming the McDonalds of computing. Cheap, mass products, available everywhere. No nutrients, no ideas, no culture. Windows 8 is a fine example. The new Metro interface displays nonstop, trivial updates from Facebook, Twitter, news sites and stock tickers. Streams of raw noise distract users from the moment they login.&lt;/p&gt;&lt;/blockquote&gt;
&lt;p&gt;The rise of sclerotic bureaucratic intermediaries isn&amp;#8217;t just a problem with Microsoft. Remember when parasitic squid were generating &lt;a rel="nofollow" target="_blank" href="http://baselinescenario.com/2009/09/01/the-nature-of-modern-finance/"&gt;40 percent of the economy&amp;#8217;s profits&lt;/a&gt;?

         <title>Does Rain Come From Life in the Clouds? | DISCOVER</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/xA_AwZltdfA/07-does-rain-come-from-life-in-the-clouds</link>
         <description>&lt;img src="http://discovermagazine.com/2012/apr/07-does-rain-come-from-life-in-the-clouds/balloonc.jpg" alt="high-altitude balloon carrying microbe collectors"&gt;
&lt;p&gt; The plane pitches violently as it plows through the milky innards of a cloud bank. A commercial pilot would fly high above these clouds over California’s Sierra Nevada Range, but this 63-foot &lt;a rel="nofollow" class="external-link" target="_blank" href="http://en.wikipedia.org/wiki/Grumman_Gulfstream_I"&gt;Gulfstream-1&lt;/a&gt; seems to invite the turbulence. Updrafts grab hold of the aircraft and shove it up even as the pilot noses it down. In the back of the plane, atmospheric chemist &lt;a rel="nofollow" class="external-link" target="_blank" href="http://atofms.ucsd.edu/"&gt;Kimberly Prather&lt;/a&gt; wears headphones to muffle the roar of the propellers. She steadies herself with a hand on an instrument rack and focuses on the bobbing screen of her laptop. Readings from the clouds spool across it.&lt;/p&gt;
&lt;p&gt;Those numbers tell Prather that these winter clouds are cold and heavy, –30 degrees Fahrenheit and just over 100 percent relative humidity. Yet despite being 62 degrees below the freezing point of water, the cloud droplets remain stubbornly liquid. As long as they don’t form ice crystals, these clouds won’t shed more than a few flakes of snow over the Sierras’ 13,000-foot peaks. They are typical clouds, teasers that won’t drop much of anything.&lt;/p&gt;
&lt;p&gt;After two hours of flying, though, something changes. The voice of another researcher crackles over Prather’s headset: “Ice!” The plane has entered a cloud layer where suddenly every droplet is frozen. Prather’s instrument—a tangle of metal tubes, wires, and airtight chambers nicknamed Shirley—tick-tick-ticks as its laser blasts apart hundreds of microscopic cloud particles, one by one, that are drawn in from the air outside. The size and composition of each particle flash across Prather’s monitor. The specks at the heart of those ice crystals are high in aluminum, iron, silicon, and titanium, the chemical signatures of dust not from California but from faraway deserts in Asia or even Africa. There’s something else in the crystals too: carbon, nitrogen, and phosphorus, telltale signs of biological cells...&lt;/p&gt;

         <title>The end of IE; the rise of Chrome | Gene Expression</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/LUfxL7ssSQI/</link>
         <description>&lt;p&gt;A comment below prompted me to recheck the browser stats on the web. People are now starting to give Google crap for not having really hit the jackpot on anything since Gmail, especially after the flubs with Google Wave and Buzz, and the mixed reviews at best for Google+. But it looks like Chrome may actually reach a plural majority this year. Back in the day (i.e., 1990s) control of the &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Browser_wars"&gt;majority browser share&lt;/a&gt; was actually a big deal. My earlier hunch that eventually Chrome will start eating into IE&amp;#8217;s user base more than Firefox&amp;#8217;s seems to be panning out.&lt;/p&gt;
&lt;p&gt;&lt;a rel="nofollow" target="_blank" href="http://blogs.discovermagazine.com/gnxp/files/2012/04/600px-Usage_share_of_web_browsers_Source_StatCounter.svg_.png"&gt;&lt;img class="alignnone size-full wp-image-16388" title="600px-Usage_share_of_web_browsers_(Source_StatCounter).svg" src="http://blogs.discovermagazine.com/gnxp/files/2012/04/600px-Usage_share_of_web_browsers_Source_StatCounter.svg_.png" alt="" width="600" height="600"/&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;He&amp;#8217;s a similar chart from the w3schools website (because it&amp;#8217;s a tech oriented site IE automatically suffers a penalty, but the overall trends are similar):&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;

         <title>Brain decoder allows monkeys to control paralysed muscles | Not Exactly Rocket Science</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/MrfexKIQ68Q/</link>
         <description>&lt;p&gt;&lt;a rel="nofollow" target="_blank" href="http://blogs.discovermagazine.com/notrocketscience/files/2012/04/Monkey.jpg"&gt;&lt;img class="aligncenter size-full wp-image-6784" title="Monkey" src="http://blogs.discovermagazine.com/notrocketscience/files/2012/04/Monkey.jpg" alt="" width="610" height="342"/&gt;&lt;/a&gt;Spinal injuries often leave people with paralysed limbs, as commands from their brains can no longer reach the muscles in their arms. So why not bypass the spine entirely? A team from Northwestern University has used a brain decoder to give monkeys control over their temporarily anaesthetised arms. The decoder deciphers the activity in the monkey&amp;#8217;s motor cortex (the part of the brain that controls movements), and electrodes in the monkey&amp;#8217;s arm stimulate its muscles in the right way. Even though it can&amp;#8217;t feel its arm, it can grab a ball using this electronic middle-man.&lt;/p&gt;
&lt;p&gt;&lt;a rel="nofollow" target="_blank" href="http://the-scientist.com/2012/04/18/brain-controls-paralyzed-muscles/"&gt;I covered this research in more detail at The Scientist&lt;/a&gt;, including some comments from a few skeptical scientists, who are concerned about the technique&amp;#8217;s limitations.&lt;/p&gt;

         <title>The Superabsorbent Nanosponge That Only Soaks Up Oil (100x Its Own Weight!) | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/VGHno3p7D3k/</link>
         <description>&lt;p&gt;&lt;br /&gt;
Using &lt;a rel="nofollow" target="_blank" href="http://blogs.discovermagazine.com/80beats/tag/carbon-nanotubes/"&gt;carbon nanotubes&lt;/a&gt; and a dash of &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Boron"&gt;boron&lt;/a&gt;, scientists at Rice University have created a &lt;a rel="nofollow" target="_blank" href="http://www.nature.com/srep/2012/120413/srep00363/full/srep00363.html"&gt;sponge that only absorbs oil&lt;/a&gt;. The superabsorbent sponge may not be of much use in the kitchen, but selective sucking of oil could be very helpful in cleaning up oil spills in the ocean. Other perks: the nanosponge is attracted to magnets, so that&amp;#8217;s they&amp;#8217;re easily controlled, and they&amp;#8217;re reusable. At the end of this video, grad student Daniel Hashim shows how to extract energy from the oil-soaked nanosponge by burning it. Then you&amp;#8217;re left with just the nanosponge, all ready to absorb oil again.&lt;/p&gt;

         <title>Bright Idea: Filling Potholes with Non-Newtonian Fluids | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/PN8inzCzk0Q/</link>
         <description>&lt;p&gt;&lt;/p&gt;
&lt;p&gt;What&amp;#8217;s something that everyone hates? That&amp;#8217;s the question that undergrads at Case Western University asked recently while brainstorming their entry for a materials science competition. Their answer: potholes. And their answer to the problem of how to fill them cheaply and easily? Basically, corn starch and water.&lt;/p&gt;
&lt;p&gt;It&amp;#8217;s not as strange as it sounds: the corn starch putty is a &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Non-Newtonian_fluid"&gt;non-Newtonian fluid&lt;/a&gt;, a class of fluids that behave very differently from water. In the case of the putty, when it&amp;#8217;s placed in an oddly shaped receptacle, like a pothole, it will flow like a liquid into all the nooks and crannies. But the second you push on it, with a car, for instance (or, as you can see in the above video, your feet), it turns solid, resisting compression and giving drivers a smooth ride.&lt;/p&gt;
&lt;p&gt;Here&amp;#8217;s a little more on the physics involved, courtesy of &lt;a rel="nofollow" target="_blank" href="http://news.sciencemag.org/sciencenow/2012/04/silly-putty-for-potholes.html?rss=1"&gt;ScienceNOW, &lt;/a&gt;including how ketchup-like non-Newtonian fluids are different from putty-like non-Newtonian fluids:&lt;/p&gt;
&lt;blockquote&gt;&lt;p&gt;Ketchup and mayonnaise are shear-thinning fluids. When sitting on your counter, they are thick and clumpy and don&amp;#8217;t flow because the particles have a tendency to stick together at rest, explains Graham. &amp;#8220;Ketchup is actually mashed up tomatoes, and it&amp;#8217;s the little particles of ...&lt;/blockquote&gt;

&lt;p&gt;I found out today that a private equity firm has &lt;a rel="nofollow" target="_blank" href="http://www.thestreet.com/story/11488145/1/yellow-pages-unlisted-from-att.html?cm_ven=GOOGLEN"&gt;purchased the majority of the Yellow Pages&lt;/a&gt; from AT&amp;amp;T. Which prompts me to ask: &lt;strong&gt;when was the last time you used the yellow pages?&lt;/strong&gt; A &lt;a rel="nofollow" target="_blank" href="http://articles.cnn.com/2010-04-02/tech/pay.phones.irpt_1_phone-booths-cell-phones-pay?_s=PM:TECH"&gt;pay phone&lt;/a&gt;? In a similar vein, &lt;a rel="nofollow" target="_blank" href="http://www.fastcompany.com/1830084/the-end-of-navigation-is-in-sight"&gt;Google And The Death Of Getting Lost&lt;/a&gt;. In 10 years (2001 to 2011) &lt;a rel="nofollow" target="_blank" href="http://www.ctia.org/advocacy/research/index.cfm/aid/10323"&gt;wireless penetration&lt;/a&gt; in the USA went from ~40 percent to ~100 percent.* This is the difference between arranging a rendezvous ahead of time in precise detail, and being confident that you can just end it with &amp;#8220;I&amp;#8217;ll call you.&amp;#8221;&lt;/p&gt;

&lt;p&gt;* This is actually calculated by comparing the number of phones to people. Since some people have multiple phones, and businesses purchase them for their employees, &amp;#8220;real&amp;#8221; penetration is somewhat less than this. I suspect that it is a larger underestimate for 2001, as a larger proportion of phones were probably business-related.&lt;/p&gt;&lt;/a&gt;

&lt;p&gt;If you thought the Kinect was just for things like &lt;a rel="nofollow" target="_blank" href="http://blogs.discovermagazine.com/discoblog/2011/07/10/not-just-sci-fi-anymore-students-create-gesture-controlled-robot-drones/"&gt;controlling flying quadrocopters&lt;/a&gt; and getting in touch with &lt;a rel="nofollow" target="_blank" href="http://blogs.discovermagazine.com/discoblog/2010/12/02/kinect-hacks-turn-invisible-make-an-instant-light-saber-more/"&gt;your inner Han Solo&lt;/a&gt;, get ready to stick your tongue out. That&amp;#8217;s right, scientists in Japan have created a Kinect game for your tongue. You wiggle it around to shoot at circles.&lt;/p&gt;
&lt;p&gt;You&amp;#8217;re &lt;em&gt;not&lt;/em&gt; running out of your house to buy the game right this second? Well, you probably weren&amp;#8217;t the target audience anyway. Japanese researchers created the game to help in diagnosis and treatment of oral motor disorders. People who have trouble speaking or swallowing could play the game to train their tongues. For the rest of us, how about a game that teaches French kissing?&lt;/p&gt;

         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/EUUFY0tf3LU/</link>
         <description>&lt;p style="text-align:center;"&gt;&lt;em&gt;&lt;a rel="nofollow" target="_blank" href="http://blogs.discovermagazine.com/notrocketscience/files/2012/04/Pinnochio.jpg"&gt;&lt;img class="aligncenter size-full wp-image-6711" title="Pinnochio" src="http://blogs.discovermagazine.com/notrocketscience/files/2012/04/Pinnochio.jpg" alt="" width="610" height="359"/&gt;&lt;/a&gt;Here’s the fourth piece from &lt;a rel="nofollow"&gt;my new BBC column&lt;/a&gt;&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;In &lt;a rel="nofollow" target="_blank" href="http://anonymouse.org/cgi-bin/anon-www.cgi/http://www.amazon.com/Truth-Machine-James-Halperin/dp/0345412885"&gt;The Truth Machine&lt;/a&gt;, a science-fiction novel published in 1996, scientists invent a device that can detect lies with perfect accuracy. It abolishes crime, changes the world, and generally saves humanity from self-destruction. Which is nice.&lt;/p&gt;
&lt;p&gt;Could such a machine ever be a reality? Not if our current technology is anything to go by. &lt;a rel="nofollow" target="_blank" href="http://anonymouse.org/cgi-bin/anon-www.cgi/http://www.apa.org/research/action/polygraph.aspx"&gt;The polygraph&lt;/a&gt; has been around for almost a century, with wired-up offenders and twitching needles becoming a staple of criminal investigations. &lt;a rel="nofollow" target="_blank" href="http://anonymouse.org/cgi-bin/anon-www.cgi/http://www.nap.edu/openbook.php?record_id=10420&amp;amp;page=212"&gt;But there is no solid evidence&lt;/a&gt; that the signs it looks for – faster heart rates, shallower breaths and moist skin – can accurately indicate whether someone is telling a lie. Underpinned by fluffy theory and backed by a weak and stagnant evidence base, this lie-detection device is unlikely to get any better.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Inside the brain&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Abandoning the polygraph, some scientists have turned to brain scanners. Two technologies have dominated the field. The first uses electronic sensors on a person’s scalp to measure an electrical signal, or “brainwave”, called the &lt;a rel="nofollow" target="_blank" href="http://anonymouse.org/cgi-bin/anon-www.cgi/http://news.bbc.co.uk/2/hi/health/3330601.stm"&gt;P300&lt;/a&gt;, which appears when we recognise something. By looking for this signal, you ...

&lt;em&gt;The Principality of Sealand and data haven? &lt;/em&gt;&lt;/p&gt;
&lt;p&gt;Seven miles off the English coast and just 24 feet above the roiling waves of the North Sea is the &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Principality_of_Sealand"&gt;Principality of Sealand&lt;/a&gt;. The nation&amp;#8217;s total area amounts to just 120 x 50 feet, but its occupier and &amp;#8220;ruler&amp;#8221; since 1966, Major Paddy Royal Bates, has had outsized dreams for his former military platform out in the sea. Once, it was the home of HavenCo, that company that billed itself as a &amp;#8220;data haven,&amp;#8221; the Switzerland of data centers.&lt;/p&gt;
&lt;p&gt;HavenCo was supposedly to be the home of businesses who didn&amp;#8217;t want governments minding their business: porn, anonymous currencies, governments in exile. When Fox News reported that &lt;a rel="nofollow" target="_blank" href="http://blog.foreignpolicy.com/posts/2012/02/01/wikileaks_to_move_to_sealand"&gt;WikiLeaks was moving its servers to Sealand&lt;/a&gt;, it certainly seemed fitting but, alas, turned out to be just speculation. That led us to &lt;a rel="nofollow" target="_blank" href="http://arstechnica.com/tech-policy/news/2012/03/sealand-and-havenco.ars"&gt;Ars Technica&lt;/a&gt;, where law professor James Grimmelmann has written what is probably the definitive history of Sealand and HavenCo, and it is a thrilling read. A few snippets from nation&amp;#8217;s short history include a pirate radio broadcaster hurling Molotov cocktails, press wars over &amp;#8220;marooned children,&amp;#8221; and coup led by a former diamond dealer (possibly staged).&lt;/p&gt;

&lt;p&gt;In November researchers showed off the lightest material ever created:  a strong metal mesh about 25 percent less dense than the wispiest aerogel, a foamlike material that was the  old record holder. A brick-size piece of the new mesh would weigh less than a paper clip.&lt;/p&gt;
&lt;p&gt;Faced with a U.S. Department of  Defense charge to manipulate well-known materials in new ways, Alan Jacobsen, a research scientist at &lt;a rel="nofollow" target="_blank" href="http://www.hrl.com/" class="external-link"&gt;HRL Laboratories&lt;/a&gt; in California, constructed delicate lattices of polymer fibers  less than a millimeter thick. He then coated the lattices with nickel and dissolved the polymer, leaving behind the spindly metal mesh...&lt;/p&gt;

         <title>“Death Star” of Medical Technology: Proton-Beam Therapy Shows “All the Problems” in US Healthcare | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/KFIEPFXEU4w/</link>
         <description>&lt;p class="imgcapright"&gt;&lt;img src="http://blogs.discovermagazine.com/80beats/files/2012/03/hospital-e1332863484504.jpg" alt="spacing is important"/&gt;&lt;/p&gt;
&lt;p&gt;Proton-beam therapy is massively expensive&amp;#8212;$100+ million facilities, each treatment twice as much as radiation&amp;#8212;and &lt;a rel="nofollow" target="_blank" href="http://www.annals.org/content/151/8/556.short"&gt;not proven to be any safer or more effective&lt;/a&gt; than other cancer treatments. So why are U.S. hospitals racing to build new proton-beam facilities?&lt;/p&gt;
&lt;p&gt;Financial incentives, and the wrong ones, according to a &lt;a rel="nofollow" target="_blank" href="http://www.bloomberg.com/news/2012-03-26/prostate-cancer-therapy-too-good-to-be-true-explodes-health-cost.html"&gt;skeptical piece at &lt;em&gt;Bloomberg&lt;/em&gt;&lt;/a&gt;. To house the 200-ton cyclotron that accelerates protons to 93,000 miles per second, the facilities have to be as big as football fields, with 16-feet-thick concrete walls. Hospitals can afford to build them because proton-beam therapy is &amp;#8220;extremely favorably reimbursed&amp;#8221; by Medicare and many private insurance companies, says Sean Tunis, CEO of the Center for Medical Technology Policy. To foot the construction bill, hospitals will have to push the treatment aggressively to cancer patients.&lt;/p&gt;
&lt;p&gt;Proton-beam therapy has been around since the 1990s, but its oft-touted safety over radiation has not been conclusively proven. In theory, proton beams are more precise than the X-rays of radiation, so proton-beam therapy has become the favored option for body parts where stray beams can be especially harmful: brain, eyes, spine, prostate. A recent &lt;a rel="nofollow" target="_blank" href="http://unclineberger.org/news/chen-presents-prostate-study-abstract"&gt;University of North Caroline study&lt;/a&gt; on patients with prostate cancer did not find proton-beam therapy ...

         <title>3-D Printers Spit Out Fancy Food, Green Cars, and Replacement Bones | DISCOVER</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/dom10L3PNHk/31-3-d-printers-spit-out-fancy-food-and-green-cars</link>
         <description>&lt;p&gt;Machines that can instantly  produce everything from food to flowers are a staple of science fiction. Today do-it-yourselfers have brought the fantasy to life with 3-D printers that lay down thin layers of material, be it plastic or cookie dough, that accumulate atop each other to create any desired shape. The printers, which cost about $1,000, work much like their ink-jet counterparts: A reservoir of material serves as a cartridge, and digital blueprints programmed in advance control the output. The printers can produce objects from model planes to robot toys in layers, in some cases spitting out glue to affix each new layer like frosting on a tiered cake. The technique has been used since the 1980s by manufacturers for rapid prototyping of models and parts.&lt;/p&gt;
&lt;p&gt;Now 3-D printing is also finding creative applications in the lab, where scientists are using the advancing technology to help design gourmet snacks, set broken bones, and build cars.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Design Nutritious Cuisine &lt;/b&gt;&lt;/p&gt;
&lt;p&gt;After the &lt;a rel="nofollow" class="external-link" target="_blank" href="http://www.fabathome.org/"&gt;Fab@Home Project&lt;/a&gt;&amp;nbsp;at Cornell University put 3-D printing instructions online, amateur craftsmen began writing in about their creations. Some had tried using materials like cake frosting and asked Cornell for help. So in 2010 Fab@Home teamed with the French Culinary Institute to fill their printer’s syringes with goopy foods that could serve as cartridge ink for shapely snacks and started making rocket ship cookies and turkey cubes. The product could then be fried, baked, or flambéed. To maintain the design, cookies were chilled before baking, and meat was coated in tasteless glue. Researchers aim to use 3-D printing to improve nutrition by precisely controlling ingredients and making healthy food more palatable for picky eaters...&lt;/p&gt;

         <title>The Bionic Limb Revolution? Not So Fast | 80beats</title>

         <description>&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;A monkey controls his robotic arm with a brain-machine interface. &lt;/em&gt;&lt;/p&gt;
&lt;p&gt;If this monkey can eat marshmallows with his robotic arm, mind-controlled prosthetics for humans can&amp;#8217;t be far off, right? Well, that&amp;#8217;s true if all you ever wanted to do with your prosthetic was sit strapped in a chair reaching for marshmallows. But as Michael Chorost explains in a&lt;a rel="nofollow" target="_blank" href="http://www.wired.com/wiredscience/2012/03/ff_prosthetics/all/1"&gt; recent feature for &lt;em&gt;Wired&lt;/em&gt;&lt;/a&gt;, challenges abound when building an arm that works in everyday life.&lt;/p&gt;
&lt;p&gt;Over the course of a day, you might use your arm to pick up a chair, unzip your jacket, or scratch your neck&amp;#8212;each one of these actions are unique. But statistical algorithms used now can translate the firing of neurons into only a few stereotyped motions. And it&amp;#8217;s not just about writing better algorithms; it&amp;#8217;s an input problem too. Getting electrodes to pick up signals from the same neurons over time is a continuous battle against the body&amp;#8217;s natural defenses:&lt;br /&gt;
&lt;/p&gt;
&lt;blockquote&gt;&lt;p&gt;Electrodes are made of metal. The body is loaded with water, salt, and a dizzying array of other chemicals. Putting them together is like trying to bond a fork and a steak. And the steak fights back by trying to dissolve the fork.&lt;/p&gt;
&lt;p&gt;The steak treats the fork as ...&lt;/blockquote&gt;

         <content:encoded><![CDATA[<p>Can you think of any?</p>
<p>Here&#8217;s what I mean.  When we set about justifying basic research in fundamental science, we tend to offer multiple rationales.  One (the easy and most obviously legitimate one) is that we&#8217;re simply curious about how the world works, and discovery is its own reward.  But often we trot out another one:  the claim that applied research and real technological advances very often spring from basic research with no specific technological goal.  Faraday wasn&#8217;t thinking of electronic gizmos when he helped pioneer modern electromagnetism, and the inventors of quantum mechanics weren&#8217;t thinking of semiconductors and lasers.  They just wanted to figure out how nature works, and the applications came later.</p>
<p><a rel="nofollow" target="_blank" href="https://cdsweb.cern.ch/record/1406073"><img src="http://blogs.discovermagazine.com/cosmicvariance/files/2012/03/higgs-cms.jpg" alt="" title="higgs-cms" width="387" height="259" class="alignright size-full wp-image-8050"/></a>So what about contemporary particle physics, and the Higgs boson in particular?  We&#8217;re spending a lot of money to look for it, and I&#8217;m perfectly comfortable justifying that expense by the purely intellectual reward associated with understanding the missing piece of the Standard Model of particle physics.  But inevitably we also mention that, even if we don&#8217;t know what it will be right now, it&#8217;s likely (or some go so far as to say &#8220;inevitable&#8221;) that someday we&#8217;ll invent some marvelous bit of technology that makes crucial use of what we learned from studying the Higgs.</p>
<p>So &#8212; anyone have any guesses as to what that might be?  You are permitted to think broadly here.  We&#8217;re obviously not expecting something within a few years after we find the little bugger.  So imagine that we have discovered it, and if you like you can imagine we have the technology to create Higgses with a lot less overhead than a kilometers-across particle accelerator.  We have a heavy and short-lived elementary particle that couples preferentially to other heavy particles, and represents ripples in the background field that breaks electroweak symmetry and therefore provides mass.  What could we possibly do with it?  </p>
<p>Specificity and plausibility will be rewarded.  (Although there are no actual rewards offered.)  So &#8220;cure cancer&#8221; gets low marks, while &#8220;improve the rate of this specific important chemical reaction&#8221; would be a lot better.  </p>
<p>Let your science-fiction-trained imaginations rome, and chime in.</p>

         <title>The FAA Might (Eventually) Allow Kindles and iPads During Takeoff | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/CASVXDYB3kw/</link>
         <description>&lt;p class="imgcapright"&gt;&lt;img src="http://blogs.discovermagazine.com/80beats/files/2012/03/iphone-airplne.jpg" alt="spacing is important"/&gt;&lt;/p&gt;
&lt;p&gt;Those of you who&amp;#8217;ve always suspected that it can&amp;#8217;t hurt to use an iPad during takeoff may finally see that claim put to the test.When &lt;em&gt;New York Times &lt;/em&gt;reporter Nick Bilton &lt;a rel="nofollow" target="_blank" href="http://bits.blogs.nytimes.com/2012/03/18/disruptions-time-to-review-f-a-a-policy-on-gadgets/"&gt;pestered the FAA&lt;/a&gt; about takeoff and landing polices for electronics, the agency seemed to be contemplating changes in the blanket &amp;#8220;turn if off&amp;#8221; rule. The last time electronic devices were comprehensively tested on airplanes was 2006, when iPads and Kindles did not yet, well, exist.&lt;/p&gt;
&lt;p&gt;But don&amp;#8217;t get too excited about your next flight. Getting tablets through the bureaucratic thicket is not trivial, as Bilton explains:&lt;/p&gt;
&lt;blockquote&gt;&lt;p&gt;[T]he current guidelines require that an airline must test each version of a single device before it can be approved by the F.A.A. For example, if the airline wanted to get approval for the iPad, it would have to test the first iPad, iPad 2 and the new iPad, each on a separate flight, with no passengers on the plane.&lt;/p&gt;
&lt;p&gt;It would have to do the same for every version of the Kindle. It would have to do it for every different model of plane in its fleet. And American, JetBlue, United, Air Wisconsin, etc., would have to do the ...&lt;/blockquote&gt;

         <title>Building a Personal Timeline Like Facebook’s, in the Privacy of Your Own Computer | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/AJtXxRigrNw/</link>
         <description>&lt;p&gt;Chances are, your hard drive is packed with important relics&amp;#8212;the first email you sent your spouse, the photographs of your grandma&amp;#8217;s 80th birthday, the documents you read for your senior thesis. The data you&amp;#8217;ve accrued plays the same role as albums full of pictures, letters, and sentimental objects might have for earlier generations: it constructs a narrative about your progress through life. Or at least it could, if there were a way to have it automatically organized.&lt;/p&gt;
&lt;p&gt;This personal data-mining is what what Facebook&amp;#8217;s Timeline feature aims to do, but the Timeline is curated manually by the user, includes only files you&amp;#8217;ve uploaded to Facebook, and is public, for all your Facebook friends to see (and maybe there are some events in your life you&amp;#8217;d like to remember without the whole world peering over your shoulder). So we were interested to &lt;a rel="nofollow" target="_blank" href="http://www.technologyreview.com/computing/39917/page1/"&gt;read about Lifebrowser&lt;/a&gt;, a product being developed in Microsoft Research that automatically arranges your hard drive&amp;#8217;s files into a timeline, using machine learning to discern which of them represent landmark events.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;We like this idea, but here&amp;#8217;s one thing we don&amp;#8217;t get: People burn through hard drives and computers like nobody&amp;#8217;s business, and once you transfer your backed-up files to ...

&lt;p&gt;Sometime this August, a six-wheeled, sedan-size mars  rover named Curiosity should begin rolling across the surface of the Red Planet. The vehicle, carried to its destination  aboard the Mars Science Laboratory, will start its journey  on the floor of Gale Crater, a 96-mile-wide depression marked with channels suggesting a watery past. But scientists have not yet decided exactly what Curiosity and its versatile suite of instruments, including the ChemCam, will explore first.&lt;/p&gt;
&lt;p&gt;Mounted atop the rover’s mast, ChemCam’s &lt;b&gt;infrared laser&lt;/b&gt; can focus a pulse of energy equivalent to the output of a million lightbulbs on a target as far as 25 feet away. At the beginning of each Martian day, scientists will choose a zone of interest, such as an intriguing rock outcrop, and instruct the rover to fire pulses around the area. Each time the laser hits rock, the impact point will erupt into a tiny ball of plasma, explains principal investigator Roger Wiens of the Los Alamos National Laboratory in New Mexico...&lt;/p&gt;

         <title>Remote-Controlled Robot Survives Encounter With Lion; Has Pictures to Prove It | 80beats</title>

How does a wildlife photographer survive such a close encounter with a lion&amp;#8217;s mouth?&lt;/p&gt;
&lt;p&gt;By outsourcing the work to this intrepid little fella. The BeetleCam is an armored, remote-controlled buggy with an a DSLR camera inside.&lt;br /&gt;
&lt;a rel="nofollow" target="_blank" href="http://blogs.discovermagazine.com/80beats/files/2012/03/beetlecam1.jpg"&gt;&lt;img class="alignleft size-large wp-image-35782" src="http://blogs.discovermagazine.com/80beats/files/2012/03/beetlecam1-610x342.jpg" alt="" width="610" height="342"/&gt;&lt;/a&gt;&lt;br /&gt;

         <title>Superfast 3D Printing Yields Tiny Racecar, Church, Bridges | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/XRlQkV08jyI/</link>
         <description>&lt;p class="imgcapright"&gt;&lt;img src="http://blogs.discovermagazine.com/80beats/files/2012/03/3D_Indy-600.jpg" alt="car"/&gt;&lt;/p&gt;
&lt;p&gt;This tiny speed racer measures 285 microns long and was 3D printed using &lt;a rel="nofollow" target="_blank" href="http://www.tuwien.ac.at/en/news/news_detail/article/7444/"&gt;a new technique developed at Vienna University of Technology&lt;/a&gt;. The printer pumps out thin lines and layers of resin, which harden when hit with a pair of photons from a laser, a kind of 3D printing called two-photon lithography. By adjusting the way the laser is produced and tweaking the formula for the resin, the team managed to make the hardening process much faster, so that what used to take hours can now take seconds. The printer can now shoot out five-meters&amp;#8217; worth of resin&amp;#8212;in an extremely fine line, of course&amp;#8212;per second. Conventional 3D printers of this sort, on the other hand, produce in millimeters per second. You can watch the racecar being made here:&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;To strut their printer&amp;#8217;s stuff, the team also made miniature models of a church in Vienna and a local bridge:&lt;/p&gt;

         <title>Cyborg Snails Generate Electrical Power From Their Blood-like Fluid | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/uuFgK9uJEn0/</link>
         <description>&lt;p class="imgcapright"&gt;&lt;img src="http://blogs.discovermagazine.com/80beats/files/2012/03/snail.jpg" alt="snail"/&gt;&lt;br /&gt;
One of the snails in question.&lt;/p&gt;
&lt;p&gt;Just a few weeks ago we wrote about scientists who&amp;#8217;d manage to &lt;a rel="nofollow" target="_blank" href="http://blogs.discovermagazine.com/discoblog/2012/02/06/how-to-turn-a-cockroach-into-a-mobile-and-kind-of-gross-fuel-cell/"&gt;draw power from the body fluids of cockroaches&lt;/a&gt;. Now, another team has &lt;a rel="nofollow" target="_blank" href="http://pubs.acs.org/doi/abs/10.1021/ja211714w"&gt;reported achieving a similar feat with snails&lt;/a&gt;: a tiny biofuel cell implanted in the creatures draws glucose and oxygen from their hemolymph (the snail equivalent of blood) to generate power. And a yet-to-be-released study, &lt;a rel="nofollow" target="_blank" href="http://www.nature.com/news/cyborg-snails-power-up-1.10210"&gt;Nature News reports&lt;/a&gt;, will feature beetles as the carriers of these minute power cells. All of this tiny cyborg excitement can be traced back to &lt;a rel="nofollow" target="_blank" href="http://pubs.acs.org/doi/abs/10.1021/ja0346328"&gt;a 2003 paper&lt;/a&gt;, in which scientists generated power from a grape. Importantly, all of these biological generators&amp;#8212;except, presumably, the grape&amp;#8212;survived and thrived after their operations.&lt;/p&gt;
&lt;p&gt;Now, we&amp;#8217;re not talking about enough power here to run your cell phone or electric car. The snail cyborg can only produce about 0.16 microwatts of continuous power, though it can rise to more than 7 microwatts for short bursts (your average lightbulb consumes 60 watts). But if developed further, such biological generation could eventually be enough for the purposes of the military, which is interested in tiny spies that can crawl into nooks and crannies of buildings or ...

         <title>Will we ever restore sight to the blind? | Not Exactly Rocket Science</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/pt24F0CbSXw/</link>
         <description>&lt;p style="text-align:center;"&gt;&lt;em&gt;&lt;a rel="nofollow" target="_blank" href="http://blogs.discovermagazine.com/notrocketscience/files/2012/03/Retinal_prosthetic.jpg"&gt;&lt;img class="aligncenter size-full wp-image-6544" title="Retinal_prosthetic" src="http://blogs.discovermagazine.com/notrocketscience/files/2012/03/Retinal_prosthetic.jpg" alt="" width="610" height="349"/&gt;&lt;/a&gt;Here&amp;#8217;s the third piece from &lt;a rel="nofollow"&gt;my new BBC column&lt;/a&gt;&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;A 46 year-old man called Miikka spotted a simple spelling mistake. A group of scientists had misspelled his name as Mika. He told them as much, and they responded with delight. Why? It was the clearest evidence yet that Miikka, who had been blind for many years, &lt;a rel="nofollow" target="_blank" href="http://www.bbc.co.uk/news/health-11670044"&gt;might be able to see again&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;This miracle is thanks to a pioneering chip implanted in his retina. Just as cochlear implants have restored hearing to people once considered deaf, devices like this are being developed that can restore sight to the blind.&lt;/p&gt;
&lt;p&gt;Miikka suffers from a particular form of blindness called retinitis pigmentosa, an inherited disease that gradually destroys the light-detecting cells of the retina. As the cells die, a person’s field of view begins to collapse from the edges. Miikka’s case was so advanced that he could only sense the direction of a bright light, and he needed a cane to get around.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Success in sight&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;That changed when German scientists led by &lt;a rel="nofollow" target="_blank" href="http://www.eye.uni-tuebingen.de/zrenner"&gt;Eberhart Zrenner&lt;/a&gt; implanted the tiny chip in his retina. The chip consists of 1,500 light-detecting electrodes, which stand in ...

         <title>What Do You Do With a Sunken Cruise Ship? | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/WP9UkWk08a8/</link>
         <description>&lt;p class="imgcapright"&gt;&lt;img src="http://blogs.discovermagazine.com/80beats/files/2012/03/costa-concordia-e1331223764216.png" alt="spacing is important"/&gt;&lt;br /&gt;
A schematic of where the &lt;em&gt;Costa Concordia&lt;/em&gt; sits on the sea floor.&lt;/p&gt;
&lt;p&gt;Nearly two months since the &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Costa_Concordia_disaster"&gt;&lt;em&gt;Costa Concordia&lt;/em&gt; capsized&lt;/a&gt; off the coast of Italy, clean-up crews are still puzzling over what to do with the gigantic wreck.  And gigantic it is&amp;#8212;with a &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Gross_tonnage"&gt;gross tonnage&lt;/a&gt; of 112,000, the &lt;em&gt;Costa Concordia&lt;/em&gt; is twice the size of the &lt;em&gt;Titantic&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;The immediate concern was oil, &lt;a rel="nofollow" target="_blank" href="http://www.telegraph.co.uk/news/worldnews/europe/italy/9047774/Costa-Concordia-will-take-10-months-to-be-removed.html"&gt;500,000 toxic gallons&lt;/a&gt; of it, that could gush into the Mediterranean. Since February 12, the Dutch film Smit has been vacuuming out fuel using a system of pumps and valves. Their work is especially tricky because the wrecked ship sits on the edge of a 200-foot underwater drop-off, and any disturbances can easily push it over. So to minimize the risk of destabilizing the ship while moving 500,000 gallons of oil out of it, Smit is pumping in seawater as it pumps out oil.&lt;/p&gt;
&lt;p&gt;Once the fuel is all extracted, crews salvaging the actual ship will have to contend with the precipitous problem too. The cruise&amp;#8217;s parent company recently invited 10 firms to bid on the clean-up operation. &lt;a rel="nofollow" target="_blank" href="http://www.scientificamerican.com/article.cfm?id=raise-it-or-raze-it-how-will-italian-cruise-ship-be-salvaged"&gt;Charles Choi at &lt;/a&gt;&lt;em&gt;&lt;a rel="nofollow" target="_blank" href="http://www.scientificamerican.com/article.cfm?id=raise-it-or-raze-it-how-will-italian-cruise-ship-be-salvaged"&gt;Scientific American&lt;/a&gt; &lt;/em&gt;talked to some experts about possible solutions.&lt;/p&gt;
&lt;p&gt;The two most practical solutions seem ...

         <title>Videos: Cheetah v. Dog v. Ostrich at the DARPA Headless Robot Zoo | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/laganvV-_os/</link>
         <description>&lt;p&gt;&lt;/p&gt;
&lt;p&gt;The latest in DARPA&amp;#8217;s ever-evolving line of headless robots is this cheetah right here. Clocking in at 18 miles per hour, it&amp;#8217;s the fastest land robot ever. Watch it go to work on that treadmill!&lt;/p&gt;
&lt;p&gt;Cheetah comes from the same collaboration, &lt;a rel="nofollow" target="_blank" href="http://www.bostondynamics.com/"&gt;Boston Dynamics&lt;/a&gt; and &lt;a rel="nofollow" target="_blank" href="http://www.darpa.mil/"&gt;DARPA&lt;/a&gt;, that brought you BigDog and AlphaDog. They aren&amp;#8217;t as fast, but what they lack in speed, they make up for in resilience. If you need someone&amp;#8212;erh, some robot&amp;#8212;to carry heavy loads across rough terrains, these robot &amp;#8220;dogs&amp;#8221; are the way to go.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Watch BigDog tramp through snow, get kicked, and otherwise abused&amp;#8212;just to get up and keep going.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;AlphaDog:&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;If speed is still what you&amp;#8217;re after though, it&amp;#8217;s time to leave the robot mammalian kingdom and look toward &lt;a rel="nofollow" target="_blank" href="http://www.ihmc.us/groups/fastrunner/"&gt;FastRunner&lt;/a&gt; the robot ostrich. Modeled after the fastest two-legged creature, FastRunner will run at 22 mph, faster than the cheetah. Confusingly, flesh and blood cheetahs still run faster than ostriches, which is why we have this video of &lt;a rel="nofollow" target="_blank" href="http://www.youtube.com/watch?v=8oV6SqyemCk"&gt;cheetahs hunting down an ostrich&lt;/a&gt; in Africa. Robot rematch?&lt;/p&gt;
&lt;p&gt;FastRunner simulation:&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;FastRunner prototype:&lt;/p&gt;

         <title>What’s That in Your Pocket? Is That a Speeeeeech……Jammmm….. | Discoblog</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/Eih4XzOOE_o/</link>
         <description>&lt;p class="imgcapright"&gt;&lt;img src="http://blogs.discovermagazine.com/discoblog/files/2012/03/speechjammer.jpg" alt="spacing is important"/&gt;&lt;/p&gt;
&lt;p&gt;Who hasn&amp;#8217;t suffered a fool who won&amp;#8217;t shut up? Suffer no more&amp;#8212;Japanese scientists have invented a portable SpeechJammer that they say can get someone to stop talking mid-sentence.&lt;/p&gt;
&lt;p&gt;The device described in a paper on &lt;a rel="nofollow" target="_blank" href="http://arxiv.org/abs/1202.6106"&gt;arXiv&lt;/a&gt; is nothin&amp;#8217; fancy. It&amp;#8217;s basically a speaker and a mic that work together to exploit a neat psychological trick: if your speech is played back with a slight delay, it becomes really hard to keep talking. The SpeechJammer works with a delay of 0.2 seconds but anything up to &lt;a rel="nofollow" target="_blank" href="http://itre.cis.upenn.edu/myl/Yates1963.pdf"&gt;1.4 seconds&lt;/a&gt; (pdf) also works. Because your brain relies on auditory feedback when you speak, the slight, very unnatural delayed feedback screws with the cognitive process.&lt;/p&gt;
&lt;p&gt;According to the authors, this technique also has the advantages of only affecting the speaker and afflicting no physical damage. Unfortunately, it doesn&amp;#8217;t work on non-word sounds, like yelling or humming. Sorry to get your hopes up, parents of screaming toddlers.&lt;/p&gt;
&lt;p&gt;If you haven&amp;#8217;t got a SpeechJammer handy, here&amp;#8217;s a neat way to test this trick yourself:&lt;/p&gt;

Go to Gchat.
Start a chat with this bot: echo@bot.talk.google.com. 
Try talking to yourself.

&lt;p&gt;Ahh weird! The echo bot&amp;#8212;designed to test audio and visual quality for videochatting&amp;#8212;does exactly what its name suggests it does. ...

&lt;blockquote&gt;&lt;p&gt;Google+ became the fastest growing social network within months of its debut last June, but a recent study casts doubt on whether most of its users are spending much time on the site.&lt;/p&gt;
&lt;p&gt;According to ComScore, &lt;b&gt;users spent an average of just 3.3 minutes on Google+ in the month of January&lt;/b&gt;, a decline from its recent figures and a tiny sliver of Facebook’s total.
&lt;/p&gt;&lt;/blockquote&gt;
&lt;p&gt;I accept the argument of &lt;a rel="nofollow" target="_blank" href="http://blogs.scientificamerican.com/thoughtful-animal/"&gt;friends&lt;/a&gt; that G+ and Facebook are fundamentally different, and that Google&amp;#8217;s aim here is not to replicate Facebook. But I also think that this is well short of what Google was intending for G+ at this stage; otherwise they would surely have quashed the media bubble and hyperbole which crested last summer. G+ is obviously much better than Buzz. But that&amp;#8217;s a low bar.&lt;/p&gt;

         <content:encoded><![CDATA[<p><a rel="nofollow" target="_blank" href="http://www.downloadtheuniverse.com/dtu/2012/03/worlds-without-end.html">My first contribution to Download the Universe</a>, our collaborative site that <a rel="nofollow" target="_blank" href="http://blogs.discovermagazine.com/cosmicvariance/2012/02/21/books-made-from-electrons/">reviews ebooks on science</a>, is now up.  It&#8217;s a review of <em>Journey to the Exoplanets</em>, a snazzy and fun iPad app from <em>Scientific American</em>.  Teaser:</p>
<blockquote><p>When I was your age, we didn&#8217;t have any of these fancy hand-held portable ebook readers. We didn&#8217;t have any such thing as extrasolar planets, either.  Planets orbited the Sun, and books were printed on paper. And we liked it that way.</p>
<p>I&#8217;m assuming here I was about your age in 1992 or maybe earlier, because that&#8217;s when the world changed forever.  Sony introduced a &#8220;portable&#8221; device called the <a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Data_Discman">Data Discman</a>, arguably the first hand-held ebook reader. That same year, Alex Wolszczan and Dale Frail made the first discovery of extrasolar planets, orbiting a pulsar with the romantic name of <a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/PSR_B1257%2B12">PSR 1257+12</a>.</p>
<p>It&#8217;s been a busy twenty years.  Everyone and their dog is reading ebooks, and astronomers are discovering planets around other stars (<a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Extrasolar_planet">exoplanets</a> for short) by the bushelful &#8212; 760 as of this writing, if we go by the <a rel="nofollow" target="_blank" href="http://exoplanet.eu/">Extrasolar Planets Encyclopedia</a>.  Which is why it seems perfectly appropriate that one of the first and snazziest ebooks devoted to science is <a rel="nofollow" target="_blank" href="http://www.the-exoplanets.com/"><em>Journey to the Exoplanets</em></a>, written by Edward Bell and illustrated by Ron Miller.</p></blockquote>

         <description>&lt;p&gt;The savvy Web user knows that the Internet isn&amp;#8217;t all fun and games. There are plenty of companies out there watching every move a user makes, with an aim to sending their way ads they will click on. But just how many companies are tracking you can be shocking, especially when you don&amp;#8217;t know what they know about you, and you have never in your life heard of them before.&lt;/p&gt;
&lt;p&gt;On Wednesday Alexis Madrigal of The Atlantic &lt;a rel="nofollow" target="_blank" href="http://www.theatlantic.com/technology/archive/2012/02/im-being-followed-how-google-151-and-104-other-companies-151-are-tracking-me-on-the-web/253758/"&gt;published a piece&lt;/a&gt; he had been working on at least since January, when he &lt;a rel="nofollow" target="_blank" href="https://twitter.com/#!/alexismadrigal/status/160435615933022208"&gt;first tweeted about Collusion&lt;/a&gt;, a plug-in built by a Mozilla engineer that keeps a record of all the sites you have been to in a browsing session and all of their ghostly, behind-the-scenes counterparts: the sites that keep track of what you do on each site. I &lt;a rel="nofollow" target="_blank" href="http://www.mozilla.org/en-US/collusion/"&gt;installed Collusion&lt;/a&gt; when I saw his tweet, and I immediately saw that visiting a single site could pick me up more than 20 trackers.&lt;/p&gt;
&lt;p&gt;But when I read &lt;a rel="nofollow" target="_blank" href="http://www.theatlantic.com/technology/archive/2012/02/im-being-followed-how-google-151-and-104-other-companies-151-are-tracking-me-on-the-web/253758/"&gt;his essay&lt;/a&gt; yesterday, the feeling of navel-gazing fascination&amp;#8212;Wow! all this time I didn&amp;#8217;t know that many people were watching me!&amp;#8212;morphed into a pretty deep frustration. Here is an account of what Collusion ...

         <title>How to Peek Inside Containers and Detect Bombs? Try Lasers | 80beats</title>
         <link>http://feedproxy.google.com/~r/DiscoverTechnology/~3/Iqma_fHtjF0/</link>
         <description>&lt;p class="imgcapright"&gt;&lt;img src="http://blogs.discovermagazine.com/80beats/files/2012/02/Raman-e1330552768555.jpg" alt="spacing is important"/&gt;&lt;br /&gt;
The Raman spectrometer emits a laser beam.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;What&amp;#8217;s the News&lt;/strong&gt;: Using a laser, a super-strong telescope, and some physics know-how, researchers say they have impressive power to look through solid barriers. Scientists have &lt;a rel="nofollow" target="_blank" href="http://dx.doi.org/10.1021/ac2021008"&gt;developed a technique&lt;/a&gt; to do so using Raman scattering, which is the change in energy of photons bouncing off a material. The technique could be used to detect hidden explosives or do geological analysis.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;How the Heck? &lt;/strong&gt;&lt;/p&gt;

A clever set-up and powerful detector telescopes were the key advancements in this study. The physics of Raman scattering itself is nothing new&amp;#8212;a &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/C._V._Raman"&gt;Nobel Prize was awarded in 1930 for its discovery&lt;/a&gt;.
To understand what&amp;#8217;s clever about the study though, we do have to get into how Raman scattering works. Photons usually bounce off a molecule unchanged in &amp;#8220;&lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Elastic_scattering"&gt;elastic scattering&lt;/a&gt;&amp;#8220;&amp;#8212;same energy, same color. In a very small number of cases&amp;#8212;and that&amp;#8217;s why you need powerful telescopes to detect it&amp;#8212;you have Raman scattering: The photon actually picks up or loses some energy from the molecule and scatters in a different color. Different materials cause different shifts in energy, which can be a signature used to detect explosives.
The researchers put &lt;a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Sodium_chlorate"&gt;sodium chlorate&lt;/a&gt;, a white powdery chemical, in ...
